Specification of Letters Patent.

Application filed May 23.

1905. Serial No. 261,752.

used in the manufacture of concrete, and itsobject is to provide an appliance of this class which shall be of simple, strong, and inexpensive construction and in the operation of which the loadwill be securely held while in transit and discharged when desired in separate portions through four independent delivery-openings, so as to be deposited in a corresponding number of separate piles around the center of the bucket.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings, Figure 1 is aside view, in elevation, of a dumpingbucket embodying our invention; Fig. 2, a vertical central section through the same, and Fig. 3 an inverted plan view.

In the practice of our invention we construct, preferably of stout plate metal, a bucket having a body 1 of quadrangular crosssection, which is secured to and braced at its corners by angle-iron frame-bars 1, extending from its top to a quadrangular bottom frame 1". The body is open at its top, which is surrounded by a bar or plate 1", through which and through the upper portion of the body a transverse rod or bar l passes, and further extends through lugs`le for the attachmentof hooks on a hoisting rope or chain,

7 said lugs being also secured to the side plates of the body l.

The body is open at its top so as to be freely accessible for loading, and its lower end is closed by a pyramidal bottom 2, the plates of which are upwardly and inwardly inclined to an apex concentric with the body and are connected by angle-iron frame-bars 2, extending from the apex to the bottom frame l".

cntly to be described, is xed and supported in a transverse bar of the bottom frame l" and in a brace 2", extending between opposite plates of the bottom at a higher level.

A veri tical central pin 2, which serves as a pivot for the door locking and releasing frame pres- The side plates of the body extend downwardly to or near the horizontal plane of the apex of the bottom, below which plane the bodyT is entirely open on each of its sides bctween the frame-bars 1, which are outwardly inclined, so as to cause the doors to stand at a corresponding inclination and each of the four side discharge-openings is closed by an outwardly-swinging door 3, which is connected at its top to the body by hinges 3". The doors drop by their own gravity to their normal closed positions and are held therein, except when opened to discharge the load of the bucket, by downwardly-projccting stops 3", secured to the outer sides of the doors, which stops are engaged by hooks 4 on a door locking and releasing frame 4, pivoted centrally on and rotatable about the .vertical pin 2e below the bottom frame. To prevent the accidental movement of the releasing-frame and the consequent undesired disengagement of its hooks 4 from the stops of the doors. a gravity-latch 4 is pivoted to one of the doors 3 in such position as to normally engage one of the hooks of the releasing-frame on the opposite side of the hook from the stop. The construction of the locking and releasing frame in a single piece and its location below the bottom frame attain the substantial advantages in practice of avoiding the use of rocking shafts and articulated connections and of protecting the frame from liability to breakage or derangement by striking against posts or other objects in the movements of the bucket.

In the operation of our improved dumping# bucket the loaded bucket is swung to the desired location of delivery, the gravity-latch 4" raised, and the door locking and releasing frame swung upon the pin 2e by striking the front of one of its hooks 4a. rlhe doors 3 will then be released and will be swung outwardly by the weight of the load, discharging the same in four separate and independent piles or portions. It will be obvious to those familiar with the manufacture of concrete that this capacity of divided discharge will be found of substantial advantage in such manufacture. The mixed ingredients when dumped from the bucket must be spread in layers not more than six or eight inches thick and then rammed, and in the use of the ordinary buckets the load is dumped in one pile, most of which must be shoveled before it can be rammed. i In the use of our improved bucket the load i being deposited in four separate piles only TOO' the top portions or' these piles need be. pushed to the center in order to'spread the entire load or batch to the desired thickness for ramming, the time and cost of handling the material being thereby correspondingly reduced. After the load has been discharged the frame 4 is swung backto the position shown in the drawings and the gravity-latch 4 dropped, when the bucket will be in readiness to receive another load.

IVe claim as our invention and desire to secure by Letters Patent- 1. In a d umping-bucket, the combination of a quad rangular body having a lower dischargeopening in each of its sides, a pyramidal bottom, doors, each swinging outwardly opposite one of the sections oi' the bottom, and hinged to the body above one of the discharge-openings, and means for coincidently locking and unlocking all the doors.

2. In a dumping-bucket, the combination of aquadrangular body,havinga lower d ischargeopening in each of its sides` a pyramidal bottom, doors, each Swingin g outwardly opposite one of the sections of the bottom, and hinged to the body above one of the discharge-openings, and means, located below and protected by the body, for coincidently locking and unlocking all the doors.

3. In adiimping-bucket, theeombination of a quadrangular body having a lower dischargeopening in each of its sides, a pyramidal bottom, outwardly-swinging' doors, each hinged to the body above one of the discharge-openings, a frame pivoted centrall5T below the bottom, and means for engaging' said frame with, and disengaging it from, the. doors.

4. In a dumping-bucket, the combination of a q uad rangular body, havinga lower dischargeopening in cach ot' its sides, a pyramidal bottom, outwardly-swinging doors, each hinged to the body above one of the discharge-openings, downwardly-projecting stops, each fixed to one of the doors, and a frame pivoted centrally below the bottom and having hooks adapted to engage the stops of the doors.

5. In a dumping-bucket, the combination of aquadrangular body,havingalowerdischargeopening' in each of its sides, a pyramidal bottom, outwardly-swinging doors, each hinged to the body above one of the discharge-openings, down wardl y-proiecting stops, each fixed to one of' the doors, a frame pivoted centrally below the bottom and having hooks adapted to engage the stops of the doors, and a lock pivoted to one of the doors in position to engage the adjacent hook of the frame.

6. In adumping-bucket, the combination of aquadrangular body havinga lower dischargeopening in each of its sides, a pyramidal bottom, a Frame fixed to the lower portion of the bottom, an upper transverse brace secured to the bottom, a vertical pin connecting said frame and brace, outwardly-swinging doors, each hinged to the body above one ot' the dis charge-openings, and a frame pivoted on said vertical pin and carrying means for engaging with the doors.
